# Defines the following variables:
|
|
#
|
|
# PROTOBUF_FOUND - Found the Google Protocol Buffers library
|
|
# PROTOBUF_INCLUDE_DIRS - Include directories for Google Protocol Buffers
|
|
# PROTOBUF_LIBRARIES - The protobuf library
|
|
#
|
|
# The following cache variables are also defined:
|
|
# PROTOBUF_LIBRARY - The protobuf library
|
|
# PROTOBUF_PROTOC_LIBRARY - The protoc library
|
|
# PROTOBUF_INCLUDE_DIR - The include directory for protocol buffers
